It is recommended to use ProTaper Next files with a brushing motion away external root concavities, so as to facilitate flute uploading apical file progression.In very severe curvatures use the files manually in a clockwise continuous motion.Clean the instrument flutes frequently and check for signs of wear or distortion.Recommended torque control – 2.- Ncm, however it is adjustable upto 5.2Ncm based on the practitioner’s experience.Use the files in a constant rotation at 300 rpm speed with light apical pressure.If the file is loose at complete working length, continue shaping with X3 file and if necessary X4 and X5 files, gauging after each instrument change with #30, #40 or #50 hand files respectively.If the file binds at length, it indicates that the canal is shaped and ready for disinfection.Gauge the size of the foramen using a #25 size hand file.Use ProTaper Next X2 in the same manner.While using NaOCl, follow the established guidepath with ProTaper Next X1 file till working length.Allows to cut a bigger envelope of motion.More cross-sectional space for enhanced cutting.Reduced engagement due to the swaggering effect, limiting undesirable taper lock.The advantages of the rotary motion and the fact that the file contacts the canal wall at only two points are: ProTaper NEXT files produce a unique asymmetrical rotary motion. While increasing the flexibility of the file, the M-Wire technology decreases the potential for broken instruments. The M-Wire technology improves the resistance of the file to cyclic fatigue by almost 400%, when compared with other files having same tip diameter, taper and cross section. Only two points of the rectangular cross section touch the canal wall at one time, as the axis of rotation differs from the center of mass. This adds greater strength to the file as it tracks down the canal. Unlike the concentric core in ProTaper Universal File system, ProTaper NEXT features an off-center rectangular core. ProTaper NEXT Dentsply files have swaggering movement of the file and utilize the innovative M-Wire technology for strengthening NiTi.
This aids in minimizing the contact between the file and dentin, which increases the efficiency while decreasing the dangerous taper lock and the screw effect. The ProTaper Next file system utilizes increasing and decreasing percentage tapered design on a single file. ProTaper Next Files has been the gold standard in endodontics for many years and has been an effective solution for practitioners. It is a versatile and flexible system capable of handling a majority of root canal treatments, including the complex cases.
Dentsply rotary endo system pro#
This Pro Taper Next file system provides various shaping advantages through a variable tapered design on a given file, M-Wire technology and a unique offset mass of rotation. The Dentsply Protaper Next Files are rotary endodontic files made of nickel titanium, used in biomechanical preparation of the root canal system.
